Design of a small animal MR compatible PET scanner

IEEE Transactions on Nuclear Science, 1999
Using a combination of Monte Carlo simulations and experimental measurements we have designed a small-animal MRI-compatible PET (McPET) scanner for simultaneous PET imaging and MRI of mice and rats in vivo. The scanner consists of one ring of 480 LSO (Lu/sub 2/SiO/sub 5/) crystals arranged in three layers, with 160 crystals per layer.

Temperature dependence of the LabPET small-animal PET scanner [PDF]

2012 IEEE Nuclear Science Symposium and Medical Imaging Conference Record (NSS/MIC), 2012
INTRODUCTION In quantitative PET imaging it is important to correct for all image-degrading effects, for example detector efficiency variation. Detector efficiency variation depends on the stability of detector efficiency when operating conditions vary within normal limits.

YAP-(S)PET small animal scanner: Quantitative results

IEEE Transactions on Nuclear Science, 2003
At present, at the Dept of Experimental and Clinical Medicine of the University of Ferrara, the YAP-(S)PET scanner is employed in small animal SPECT studies, with 99mTc labelled radiotracers, dedicated to obtain quantitative activity measurements in a region of interest (ROI) directly from a reconstructed image of a rat, with respect to the traditional

Design Considerations for Small Animal PET Scanners

2014
Positron emission tomography (PET) is an established imaging technique currently used for the clinical management of disease in oncology, cardiology and neurology [1–3]. PET is nowadays integrated in the clinical routine and is acknowledged as a sensitive clinical molecular imaging method.

System Architecture of the LabPET Small Animal PET Scanner

IEEE Transactions on Nuclear Science, 2008
To address modern molecular imaging requirements, a digital positron emission tomography (PET) scanner for small animals has been developed at Universite de Sherbrooke. Based on individual readout of avalanche photodiodes (APD) coupled to LYSO/LGSO phoswich detectors, the scanner supports up to 4608 channels in a 16.2 cm diameter, 11.25 cm axial field ...

Raytest ClearPET™, a new generation small animal PET scanner

Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2007
The ClearPET is a high-performance small animal PET scanner that has been developed by the Crystal Clear Collaboration (CCC) and is now commercially available to customers worldwide through the Raytest group. Its high sensitivity and spatial resolution are achieved, thanks to a patented phoswich configuration made of two types of scintillating crystals:

Evaluation of the first Silicon Photomultiplier matrices for a small animal PET scanner

2008 IEEE Nuclear Science Symposium Conference Record, 2008
A high resolution small animal PET scanner that employs Silicon Photomultiplier (SiPM) matrices as photodetectors is under development at the University of Pisa. The first SiPM matrices fabricated by the Center for Scientific and Technological Research, FBK-irst, Trento, Italy, are being evaluated for this purpose.

An MR compatible PET scanner for imaging small animals

Nuclear Medicine Communications, 2004
Combined PET-CT scanners are becoming standard for clinical PET imaging. The development of a combined PET-MR scanner poses greater technological challenges. A prototype small animal MR compatible PET scanner has previously been designed, constructed and evaluated in collaboration with UCLA School of Medicine.

System electronics for the MiCES small animal PET scanner

2003 IEEE Nuclear Science Symposium. Conference Record (IEEE Cat. No.03CH37515), 2003
The final electronics system for the microcrystal element scanner (MiCES) small animal positron emission tomograph is described. Groups of four position-sensitive photomultiplier tubes (FSPMTs) are connected to an adapter board which provides four output signals from each PSPMT.

Advances in animal PET scanners.

The quarterly journal of nuclear medicine : official publication of the Italian Association of Nuclear Medicine (AIMN) [and] the International Association of Radiopharmacology (IAR), 2002
Nowadays, a growing number of research groups shows a great interest for the application of PET and SPECT techniques to the development of new drugs. Preliminary studies on small animals require high performance dedicated scanners with a higher spatial resolution and sensitivity than those of clinical systems.
